"Why have we had to invent Eden, to live submerged in the nostalgia of a lost paradise, to make up utopias, propose a future for ourselves?"

Julio Cortazar's quote explores the human psyche and its continuous yearning for an idealized state of existence-- typically embodied in the concept of Eden or paradise. The metaphor of Eden represents a perfect world, a place of origin that is pure, untainted, and harmonious. By questioning why we invent such paradises, Cortazar touches upon a basic human trait: fond memories for a world that might never have existed beyond our creativities. This nostalgia is not merely a longing for the past however a more profound reflection of human dissatisfaction with today.

People are storytellers by nature, and developing myths or thinking of paradises ends up being a coping mechanism for the viewed flaws and complexities of our present presence. It acts as both an escape and a review of reality, using a lens through which we can envision much better possibilities. This developed Eden symbolizes more than just a fictional perfect past; it is also a blueprint for our aspirations and a canvas for our hopes. It presses us to question what we genuinely worth and desire in our lives, inspiring ventures to enhance our individual and cumulative futures.

The mention of utopias and proposing futures further emphasizes the human inclination to pursue progress and enhancement. These constructs function as directing stars, illuminating courses forward even when useful results might deviate from the perfect. The development of these stories shows an intrinsic optimism and a belief in the potential for betterment, even when tempered by realism.

Cortazar's inquiry challenges us to think about the factors behind these constructs. Are they merely illusions preventing us from challenging existing issues, or are they needed visions that guide us toward meaningful modification? In essence, the quote welcomes reflection on our motivations and the double role of idealized visions as both sanctuaries and catalysts for real-world action.
